Switching

Hello.

I found that there is alot of changes in q-in-q configuration for ELS switches. My configuration in the  the lab is now working but I would like to add more "normal" vlan trunk to the same interface anyone know how to do this?

CPE (acess)<-----SW-1-ELS-SW ------> (all-trunk) SW-2 (all-trunk) ------> SW-3-ELS-SW ------> (access) CPE

With my current config below I'm not able to ping between switches in the 10.42.6.0 network.

SW-1-ELS-SW

Try using "encapsulation flexible-ethernet-services" instead of extended-vlan-bridge.

https://www.juniper.net/documentation/en_US/junos/topics/topic-map/switches-interface-flexible.html

Seems like EX4300 is not supporting this encapsulation. It's not appearing as an option.

Even though it's written about in your doc link..

Hi Sesa, 

Per doc : 

https://www.juniper.net/documentation/en_US/junos/topics/topic-map/switches-interface-flexible.html

NOTE  : For EX4300 device, the service provider style configuration (encapsulation extended-vlan-bridge) is recommended only for QinQ scenarios. For other scenarios, use the enterprise style configuration.

Can you try removing family ethernet-switching and include vlan-ids , for example:? 

facing customer
root@EX# show | display set | match ge-0/0/0
set interfaces ge-0/0/0 flexible-vlan-tagging
set interfaces ge-0/0/0 encapsulation extended-vlan-bridge
set interfaces ge-0/0/0 unit 0 vlan-id-list 4
set interfaces ge-0/0/0 unit 0 vlan-id-list 33-34
set interfaces ge-0/0/0 unit 0 vlan-id-list 3000
set interfaces ge-0/0/0 unit 0 vlan-id-list 3092
set interfaces ge-0/0/0 unit 0 vlan-id-list 3096
set interfaces ge-0/0/0 unit 0 vlan-id-list 3100
set interfaces ge-0/0/0 unit 0 vlan-id-list 3104
set interfaces ge-0/0/0 unit 0 input-vlan-map push
set interfaces ge-0/0/0 unit 0 output-vlan-map pop
set vlans VLAN-778 interface ge-0/0/0.0
 
Facing provider
root@EX# show | display set | match ge-0/0/1 
set interfaces ge-0/0/1 flexible-vlan-tagging
set interfaces ge-0/0/1 encapsulation extended-vlan-bridge
set interfaces ge-0/0/1 unit 778 vlan-id 778
set vlans VLAN-778 interface ge-0/0/1.778

Hello Franky.

Thank you this is working as intented I have tried it.

I'm facing another problem. How do I add an l3-interface to one of the vlans on the interface facing provider.

I have a case where I have to do mgmt access on the same port as q-in-q.

I have tried the config but the switch is not reachable on the assgined IP

set interfaces ae0 vlan-tagging
set interfaces ae0 mtu 9192
set interfaces ae0 encapsulation extended-vlan-bridge
set interfaces ae0 unit 426 vlan-id 426
set interfaces ae0 unit 4000 vlan-id 4000

set interfaces irb unit 426 family inet address 10.42.6.3/24

set vlans v4000 interface ge-1/0/1.0
set vlans v4000 interface ae0.4000
set vlans v426 vlan-id 426
set vlans v426 interface ae0.426
set vlans v426 l3-interface irb.426

Hi Sesa,

I'm glad the first issue got resolved!

For your second issue, I think because irb will become up when this is bounded to family-ethernet-switching interface(not sure if in your case is up or down), not vlan-ids.

set interfaces ae0 vlan-tagging
set interfaces ae0 mtu 9192
set interfaces ae0 encapsulation extended-vlan-bridge
set interfaces ae0 unit 426 vlan-id 426
set interfaces ae0 unit 4000 vlan-id 4000
set interfaces irb unit 426 family inet address 10.42.6.3/24 >>>> here!
set vlans v4000 interface ge-1/0/1.0
set vlans v4000 interface ae0.4000
set vlans v426 vlan-id 426
set vlans v426 interface ae0.426
set vlans v426 l3-interface irb.426 >>>> here!

Try this one and remove the irb interfaces.

set interfaces ae0 unit 426 vlan-id 426 family inet address 10.42.6.3/24

Try checking if the L3 is learning mac address in the other P router interface.

Please, Mark My Solution Accepted if it Helped, Kudos are Appreciated too!!!

Thank you,
Franky

Hello Franky!

Thanks again for your reply. It was my misstake, I forgot to add ae0.426 under vlans.

set vlans v426 vlan-id 426
set vlans v426 interface ae0.426
set vlans v426 l3-interface irb.426

Hello Sesa, 

Oh cool! thanks for accepting my solution, much appreciated!
